Best scenario you would like to use is (and cheapest) :

Install Solaris 11.1 (do not install beta version), it will come with Oracle VM server for sparc on all physical nodes since you currently have multiple version of Solaris in production.

Check to have everything the same version on all physical hosts, this is important (firmware, Os version etc.)

Configure it, and create as much ldoms as you need and migrate your Solaris installations on it.
Oracle VM Server for SPARC Physical-to-Virtual Conversion Tool - Oracle VM Server for SPARC 3.1 Administration Guide

Requirement is to have FC or similar tech (NFS, ISCSI), so all the physical hosts see all the network disks and are logically configured with same names on all physical hosts.

This will enable you to live migrate a ldom from host to host with no downtime or import tje configuration of ldom and boot it on another host in case of failure (you will need to backup ldom xml configuration from all physical hosts on external location).

You can, of course, have local disks ldoms, but those are prone to single host failure, but such configuration can be used if you have SC between two ldoms on two physical hosts.

In the above example, you will not be using SC, for SC scenario is much alike but then clusterware is doing all the migrations and booting in case of failure or switching.
